8.2 Different Cross Reference Commands

Used to start a sentence in the printed manual and in HTML with
‘See …’ or an Info cross reference saying ‘*Note
name: node.’.

@ref

Used within or, more often, at the end of a sentence; produces just
the reference in the printed manual and in HTML without the preceding
‘See’ (same as @xref for Info).

@pxref

Used within parentheses, at the end of a sentence, or otherwise before
punctuation, to make a reference. Its output starts with a lowercase
‘see’ in the printed manual and in HTML, and a lowercase ‘*note’
in Info. (‘p’ is for ‘parenthesis’.)

@inforef

Used to make a reference to an Info file for which there is no printed
manual.

The @cite command is used to make references to books and
manuals for which there is no corresponding Info file and, therefore,
no node to which to point. See @cite.
